Mining and infostealers: 93.3% of 15 organisations have staff logins in stealer logs

Infostealer statistics · Mining companies · October 2026

93.3% of the 15 mining companies in the Ransomnews panel have employee credentials in stealer logs in the October 2026 snapshot, against 89.4% across all 36 countries. The median organisation in the sector has 57 such credentials in circulation (31 panel-wide), 107 were captured in the 30 days before the snapshot, and 60.0% of organisations gained at least one. Mining companies rank 10th of 21 sectors with ten or more organisations by the share of organisations exposed and 4th by credentials per organisation.

How mining companies compare with the rest of the panel

Mining companies are more exposed than the panel as a whole: 93.3% of them have at least one employee credential captured by infostealer malware, against 89.4% across the panel, and the median organisation carries 57 credentials against 31. The distribution is long-tailed: 1 organisation has no employee credentials in the index, 5 have a hundred or more and 0 have a thousand or more. 8 organisations gained new credentials in the final seven days before the snapshot.

Lifetime totals accumulate over years of captures; the 30-day and 7-day figures are the measure of current activity. A stealer-log record is produced on an infected device, usually a personal or unmanaged machine where an employee saved work passwords in the browser; it means that credential is in criminal hands, not that the organisation’s own systems were breached.

Which mining companies have the most employee logins in stealer logs?

vale.com (826), angloamerican.com (463) and bhp.com (216) carry the most employee credentials in the index among the companies measured in the sector. Per-organisation figures are published for companies only; government, university and health bodies in the panel are reported in the aggregates above. The counts are logins captured from infected devices on which staff had saved their work passwords, not evidence that the company’s own systems were breached; a company with a large workforce and many contractors accumulates more of them for the same infection rate.

What do the stolen employee logins open?

A stealer takes every password saved on the infected machine, so the log that holds an employee’s email login usually holds their logins to the organisation’s cloud services too. Across the 13 organisations in the sector with such records, the services most often captured alongside a work email address are Cisco Systems (Cloud), Box and Mimecast. By category, Networking & Security (23.6%), Cloud Storage (16.1%) and Email Security & Archiving (10.1%) lead.

Service counts are summed from each organisation’s 25 largest services; categories are the index’s own labels, lightly consolidated. An identity-provider login (Okta, Entra, Ping) is the most dangerous record in this table: it opens every application behind the organisation’s single sign-on, and the stealer usually captures the session cookie next to it.

How to use these figures

Check your own domain with Stealercheck, which returns the same lifetime, 30-day and 7-day counts, and compare the result with the median above (57 for mining companies). For every exposed account: reset the password, revoke active sessions so stolen cookies stop working, re-enrol MFA and find the infected device. Then block browser password saving for work accounts in favour of a managed password manager and shorten session lifetimes on single sign-on. The controls that stop the infection itself are in our guide to ransomware protection for business.

Method. Figures come from the October 2026 snapshot of the Alerts.bar infostealer index, taken for a fixed panel of 1,874 organisation domains in 36 countries and stored by Ransomnews; the panel is held constant so that month-on-month change reflects the threat rather than the sample. Employee credentials are stealer-log records whose username is an address on the organisation’s domain (university figures include students); customer logins are credentials captured on the organisation’s own login pages; session cookies are authentication cookies harvested from infected browsers. The index reports a floor of 1 on lifetime counters, which we record as 0, and domains that host consumer mailboxes are excluded from employee figures.
